摘要： This invention provides a film-cooled internal combustion engine in which a film of gas is applied to interior surfaces of the engine to reduce heat transfer to the metal components of the engine from hot combustion gases to cause more work to be extracted from those gases, thereby raising the efficiency of the engine. In one form, this objective is achieved by reducing the temperature of the gas coming in contact with the metal parts during the power stroke of the engine by laying down a thin film of gas between the hot combustion gases and the walls of the engine. This thin film of gas creates an effectively lower film temperature-driven convection heat transfer. This invention reduces heat transfer to walls of the engine, protects hot parts, reduces knock (pre-ignition), and purges fuel from tight spaces in the engine.
摘要翻译： 本发明提供了一种薄膜冷却内燃机，其中气体膜被施加到发动机的内表面，以减少从热燃气体向发动机的金属部件的传热，从而从这些气体中提取更多的工作， 从而提高发动机的效率。 在一种形式中，通过在发动机的动力冲程期间通过在热燃烧气体和发动机的壁之间铺设气体薄膜来降低与发动机的动力冲程中的金属部件接触的气体的温度来实现该目的。 这种气体薄膜可以有效地降低薄膜温度驱动的对流热传递。 本发明减少了对发动机壁的热传递，保护了热部件，减少了爆震（预燃），并将燃料从发动机的狭窄空间中清除。

摘要： A method for removing at least one impurity from coal is described herein. The method includes providing coal comprising a plurality of impurities and contacting the coal with an acid solution in a reaction chamber. At least one of the impurities reacts with the acid solution to produce one or more first products soluble in the acid solution. The method further includes removing at least a portion of the acid solution including at least a portion of the first products from the reaction chamber and adding a nitrate composition to the reaction chamber to form a nitrate solution. At least one of the impurities, at least one of the first products, or combinations thereof react with the nitrate composition to produce one or more second products soluble in the nitrate solution. The method still further includes removing at least a portion of the nitrate solution including at least a portion of the second products from the reaction chamber.

摘要： A method for removing at least one impurity from coal is provided. The method comprises providing coal having a plurality of impurities and contacting the coal with a first leaching solution. The first leaching solution reacts with at least one of the impurities to produce one or more first products soluble in the first leaching solution. The method further comprises adding a neutralizing composition to the first leaching solution. The neutralizing composition reacts with the first leaching solution to form a precipitate. The method further comprises separating at least a portion of the first leaching solution from the coal and the precipitate and contacting the coal and the precipitate with a second leaching solution. The second leaching solution reacts with at least one of the impurities and the precipitate to form one or more second products and one or more third products, respectively, the second products and the third products being soluble in the second leaching solution. The method further comprises separating at least a portion of the second leaching solution from the coal.
